ANDREW N. ARMSTRONG, OF BLUE MOUND, ILLINOIS.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 251,811, dated January 3, 1862.

Application filed September 7, 1831.

To all trhom it may concern:

Be it known that I, ANDREW N. ARM- STRONG, acitizen of the United States, residing at Blue Mound, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Oar-(Jouplings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters or figures of reference marked thereon, which form a part of this specification.

My invention consists of a novel construction of car coupler, which will be understood by the following specification and claims.

In the accompanying drawings, Figure 1 is a side view of my improved car-coupler. Fig. 2 is a top view of the same. Fig. 3 is a bottom view.

In the construction of my car-coupling the sliding and revolving rod A is madewith two hooks or clutches, B, thereon,said hooks being set so as to faceiirppposite directions to each other. Therod A slides and revolves in metallic guide-rods G, firmly held in place by pieces of wood D, Fig. I

Attached to the rod A is a coiled spring, E, which serves the double purpose of revolving (No model.)

the rod, and thus clutching the coupling to its fellow opposite, and ol'making the rod or coupling-head an elastic butter.

0n the end of the car is a Windlass, F, provided with a ratchet, G, and dog H, in the usual manner. This Windlass has two cords, I and K, connected respectively to the hooks or clutches B B, the cord K of which passes round a pulley, L. By this means the head of the clutch and the rod A may be revolved, giving a tensile strain upon coiled spring E, and thus very s rongly locking the coupling when the two hrads are engaged.

Having thus described my car -couplin g, what I claim is The combination, with the sliding and revolviug rod A, provided with the hooks or clutches B B and spring E, of the Windlass F, having ratchet G and dog H, and the cords I and K, connecting said Windlass with the hooks or clutches B B, the cord K passing over pulley L,'the several parts constructed and relatively arranged to operate in the manner herein shown and described.

In testimony whereofl affix my signature in presence of two witnesses.
